Type your user name and password when the remote
host prompts you for it. If you are using the Secure Internet Services
version of telnet you will not be prompted for a login or password.
You must have a valid login to the remote host
in order to connect to it with telnet.
After you log into the remote host, telnet is in input state. When telnet is in input state, you can use the remote host
as if your terminal or workstation were physically connected to
that host.
If you notice that certain keystrokes do not do what you expect
them to do, see “Checking Your Remote
Terminal Configuration”.
